Josh Poimboeuf a8ff29f0ca livepatch/klp-build: Require Clang assembler >= 20 ... Some special sections specify their ELF section entsize, for example: .pushsection section, "M", @progbits, 8 The entsize (8 in this example) is needed by objtool klp-diff for extracting individual entries. Clang assembler versions older than 20 silently ignore the above construct and set entsize to 0, resulting in the following error: .discard.annotate_data: missing special section entsize or annotations Add a klp-build check to prevent the use of Clang assembler versions prior to 20.
